At the selection ceremony of the Phoenix Clan, it is revealed that Sang Ning and Chou Nu were once switched, but Liuguang readily agrees to switch back to her daughter and admits that she knew about it a long time ago. When everyone wonders why she is so heartless and desperate, Liuguang reveals an even bigger secret hidden in the aftermath of this incident.
